[image]Cassiopeia A, Chandra 3-color X-ray
This 3-color version of the Chandra First Light data displays a wealth of detail and drama. Note the shock wave on the outer edge, and the blow-out on the upper left, as well as the enigmatic bright spot in the middle. The low, medium, and higher X-ray energies of the Chandra data are shown as red, green, and blue. Credit: NASA/CXC/SAO (courtesy, C.Jones)

[movies]Three Chandra Views of Cassiopeia A - NASA/CXC/GSFC/U.Hwang et al.
MPEG This sequence shows three different sets Chandra observations of Cassiopeia A. The first image is Chandra's "First Light" image, which was released in August 1999 as the observatory's first major science image. This 5,000-second-long observation then dissolves into another image created from Chandra that contained data from 50,000 seconds of X-ray data released in 2002. Finally, the new one-million-second observation of Cassiopeia A is seen, revealing spectacular new detail and complexity t...

[image]Chandra X-Ray Observatory Image of Cassiopeia A - NASA/Marshall Space Flight Center
This is an extraordinary first image from the Chandra X-Ray Observatory (CXO), the supernova remnant Cassiopeia A, tracing the aftermath of a gigantic stellar explosion in such sturning detail that scientists can see evidence of what may be a neutron star or black hole near the center. The red, green, and blue regions in this image of the supernova remnant Cassiopeia A show where the intensity of low, medium, and high energy X-rays, respectively, is greatest...

[image]Acceleration Map of Cassiopeia A - NASA/CXC/MIT/UMass Amherst/M.D.Stage et al.
This figure shows regions in Cas A where the X-ray emission is generated by electrons spiraling along magnetic field lines and being accelerated as they pass across the remnant's shock front. In this acceleration map, the brighter parts of the image show where the acceleration is occurring relatively quickly. In the brightest areas the electrons are being accelerated almost as fast as theoretically possible...

When the supernova first appeared in November 1572, it was as bright as Venus and could be seen in the daytime. Over the next two years, the supernova dimmed until it could no longer be seen with the naked eye...

This x-ray image of the Cassiopeia A (CAS A) supernova remnant is the official first light image of the Chandra X-Ray Observatory (CXO). The 5,000-second image was made with the Advanced Charged Coupled Device (CCD) Image Spectrometer (ACIS). Two shock waves are visible: A fast outer shock and a slower irner shock. The inner shock wave is believed to be due to the collision of ejecta from the supernova explosion with a circumstellar shell of material, heating it to a temperature of 10 million-de...

These Spitzer Space Telescope images, taken one year apart, show the supernova remnant Cassiopeia A (yellow ball) and surrounding clouds of dust (reddish orange). The pictures illustrate that a blast of light from Cassiopeia A is waltzing outward through the dusty skies. This dance, called an "infrared echo," began when the remnant erupted about 50 years ago. Cassiopeia A is the remnant of a once massive star that died in a violent supernova explosion 325 years ago...

The forward shock is now located at the outer edge of the blue glow. Stars are also seen in blue. Green, yellow and red primarily represent material that was ejected in the explosion and heated by a slower shock wave, called the reverse shock wave...
